Opis (eng)

Background and aims Satureja kitaibelii Wierzb. ex Heuff.  (savory) is one of the most popular herbs in Serbia, used as a culinary plant, as well as tea in traditional medicine. The objective of this study was an analysis of seasonal variation in trace element contents in the soil and S. kitaibelii, at the Kravlje village, southeastern Serbia, with emphasis on potential aspects of health promotion. Methods We studied the total content of B, Si, Cr, Mn, Ni, Cu and Zn in the soil and savory using inductively coupled plasma-optical emission spectrometry. The obtained results were analyzed by chemometric methods: hierarchical cluster analysis (HCA) and principal component analysis (PCA). Results Chemical, statistical and chemometric analysis conrmed a variation in trace element content of studied soil and plant samples. The lowest contents of the studied elements in the soil, except for silicon, were recorded in the vegetative stage. In the plant, the boron content is the highest: 10.5-14.9 mg/kg and the chromium content is the lowest: 0.17-1.2 mg/kg. The highest values of soil-to-plant transfer factor were recorded for ve elements (except Si and Cr) in the vegetative stage. Conclusion The present study revealed that savory from Serbia can be considered an accumulator of boron and a potential source of valuable trace elements. A signicant percentage of daily intake of B, Cr and Ni, can be provided with three cups of tea per day of plants collected in the vegetative and owering stages.
